I created a custom user control and in doing so I followed the "tutorial" that I read in the SF 4 docs. I can see the new widget in the toolbox when I goto the page templates, but when I drag and drop the widget to the template, I'm getting the following error message:

'couldnot load type SitefinityWebApp.usercontrol.myUsercontrol.ascx'

the widget is just some basic HTML, how can I use this widget that i created?

Can you attach a screenshot of the Configuration settings you used to register the control and the control location in your solution?

The error you see means that the path you used to register the control is not correct. You see the widget in the list, because you have "added" a new toolbox item - new record in the configuration, but the config element does not know whether the path the control is correct or not

I cannot replicate issues with adding custom or user controls. Please take a look at attached video in one of the previous posts. It shows the process of creating and registering a control in Sitefinity. Make sure that you build the application after the control is created.

We're using SiteFinity 9.1 and I'm having trouble getting a custom user control to show up in the toolbox. I followed the tutorials and watched the video referenced here. It's a basic Hello World control. I registered through the Admin and also using Thunder. It adds the info to the toolboxes config file as the following:
